So far, right off the top of my head there are three virus theories:
1. No such thing as a virus.
2. Viruses are actually bacteria that have been named as viruses because a few scientists decided that they were too small to be called bacteria
3. And now viruses are exosomes.
An interesting note:
I have a dear friend who went to Germany to be included in a study which involved scientists who were giving her an exosome treatment. It didn't help her.
I honestly do not know if we can trust anyone anymore.
Except for: gargle with warm salt water, get fresh air, light, light exercise if and when possible and maybe some of the old, forgotten (snake oil?) remedies.

Perhaps we just need God and Jesus back!!!💛
